Natural Errors These are caused due to variations in nature i.e., variations in wind, temperature, humidity, refraction, gravity and magnetic field of the earth. The measurement of baseline has an important role in the triangulation surveying, because the accuracy of computation of sides of the triangle depends upon the accuracy of the measured E.g. e MICHELIN E PRIMACY XL 175/55R20 89Q XL June 22, 2022 . The following values were determined in a series of tape measurements of a line: 1000.58, 1000.40, 1000.38, 1000.48, 1000.40, and 1000.46 meters. Understanding that Probable Errors add in quadrature, the Probable Error in a length of time between two such measurements would then be:-+/- Squrt (0.52 + 0.52) = +/- 0.707 or +/- Squrt (0.252 +0.252 ) = +/- 0.35or +/- Squrt (0.342 +0.342 ) = +/- 0.48 ?
